Circadian Correcting Light Sources

1 product

This cyan light source is intended to address circadian entrainment (timing) and/or rhythm amplitude (a problem more commonly found with the elderly as evidenced by overly frequent napping).

Engineered by a Bio-Physicist who has spent many years studying these matters.

Cyan-colored-light is an ideal meltopic driver while avoiding the greater photo-toxicity of bright white or bright blue light which were conventionally used by earlier scientists to address circadian disruption issues.

This devise can be purchased directly from the Sunnex BioTechnologies website (located in Canada) or from this page (we are located in the USA) or in person at the Light For Fitness store in Dunkirk NY.

For the science-lover, there is much information on the Sunnex website about retina-safer-light-therapy, so I highly recommend browsing and reading the articles on that site.

 WHY 400 lux of green light from a LO-LIGHT lamp is equivalent to 6,000 to 10,000 lux of white light

Instructions for usage come with the product and are included below.

Instructions for Use of Sunnex Biotechnologies' MINI Lo-LIGHT Lamp 

Where to Place your Lo-LIGHT 

Place the unit around 18” (45 cm) from the user in a manner that the lamp is in the user's field of vision. It is not necessary to look directly at the lamp, but the user should be able to see the lamp by shifting the direction of gaze without moving their head. 

Keep Room Lighting dim 

Block sunlight from entering the room while the unit is being used, and keep interior lighting turned off. TV sets, computer monitors, and other products that emit low levels of lighting are permitted, as they will not adversely affect the treatment. 

Correct Timing is Vital for Effective use of Light Therapy 

Morning Responders - often people who find it difficult to awaken in the morning. 

The effect of light therapy is related to the time of its use with respect to the individual's internal biological clock. For most people light therapy is most effective in the morning. Start treatment at time of normal, awakening, that is the time when one would awaken if allowed to sleep until awakening by themselves, without external interference. Then advance the time of use by 15 minutes per day until one is using it at the desired time of awakening. Initially, we recommend the Lo-LIGHT be used for one hour, until one achieves the desired effect. Time of use can then be reduced by 5 to 10 a minutes a day until a sense that the influence of the light is diminishing. Most people will find 20 to 40 minutes per day is adequate. Some will need as little as 15 minutes while others need 45 minutes to an hour. 

Evening Responders people who normally awaken early and get tired early in the evening. 

About 20 percent of people are evening responders. If there is no improvement with morning treatment, a period of evening treatment should be tried. We suggest treatment time should begin around 8 pm for as close to an hour as is convenient. The length of time of use can then be reduced by 5 to 10 a minutes a day until a sense that the effect of the light is diminishing. 

NOTE: All users should immediately turn the unit off if they become agitated or develop a sense of hyper-activity during treatment. In future treatments the time of exposure should be shortened to period less than the duration of exposure at which they became agitated. 

For patients diagnosed with a bipolar disorder, we recommend starting with 10 to 15 minutes and increasing exposure time by 5 minutes a day to 30 to 45 minutes, or until the user feels the effect of the therapy or develops a sense of agitation or hyper-activity. In future treatments the time of exposure should be shortened to period less than the duration of exposure at which they became agitated. 

For some even this low intensity Mini Lo-LIGHT lamp will not be entirely comfortable at the recommended distance. We suggest these users place the unit at a distance they find comfortable as studies indicate light sensitive people can obtain the full light therapy effect at a substantially lower Green LIGHT intensity than that provided by the unit at 18 inches (45 cm).
